ATTACHING MEANS FOR RUBBERS.

To all whom it may concern:

Be it known that I, SIMON J. MCCANN, a citizen of the United States, anda resident of the city of Chicago, in the county of Cook. and State ofIllinois, have invented certain new and useful Improvements in AttachingMeans for Rubbers; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawings, and to the numbers of reference marked thereon,which form a part of this specification.

The object of this invention is to afford means whereby rubbers orover-shoes may be detachably secured to and yieldingly held in place onthe shoe, permitting the utmost freedom of movement of the foot andinsuring the retention of the rubber or overshoe in place untilintentionally removed.

It is also an object of the invention to afford a resilient devicepermanently attached to the rubber or overshoe and which acts to reducethe wear to a minimum by holding the shoe at all times securely inplace.

The invention is embodied in the matters hereinafter described and morefully pointed out and defined in the appended claims.

On the drawings: Figure 1 is a side elevation with the rubber orover-shoe partly broken away and showing the attaching means inelevation. Fig. 2 is a similar view and illustrates the use of myinvention in what may be termed a sandal. Fig. 3 is an end elevation ofthe attaching means. Fig. 4: is a top plan view thereof. Fig. 5 is alongitudinal section taken therethrough and through the sole of therubber or overshoe.

As shown in said drawings: 1, indicates the shoe, and 2, the over-shoeor rubber in which, and rigidly secured to the sole thereof, are themeans for attaching the same to the shoe. Said means, in the embodimentof my invention illustrated, comprises a resilient metallic plate 4,shaped by stamping or otherwise to afford a leaf spring, which extendslongitudinally of the rubber or over-shoe conforms to the curved shapeof the arch thereof and is secured at its ends by means of rivets to thesole thereof at the arch.

Laterally directed spring arms 5, integral with the spring plate at itsmiddle and of a length to fit snugly in the overshoe, are bent upwardlyand inwardly at the ends to Specification of Letters Patent.

Patented Sept. 5, 1911. Serial No. 563,742.

afford inwardly directed shoulders 6, adapted to engage over the sole ofthe shoe to which the rubber is to be attached. Integral with saidinwardly directed portion of said spring arms is an outwardly turnedguide end or tongue 7, which, although short, is of sufficient length topermit the wearer to insert the finger into the rubber or over-shoe toforce said spring ends outwardly to release them from the shoe sole.

The operation is as follows: In putting on the rubber or gum-shoe,whether of the type illustrated in Fig. 1 or that illustrated in Fig. 2,the foot is inserted therein as is usual and weight, when applied,presses the sole of the shoe between the lateral spring arms until theshoulders 6, engage over the sole of the shoe below the arch, ofnecessity springing the longitudinally extending spring plate upwardly,thereby exerting tension on the sole of the over-shoe or sandal andacting to hold the same securely in place. In the construction shown inFig. 2, the spring plate holds the sole of the rubber against the soleof the shoe and prevents water or dirt passing into the rubber.

My invention has a further function in connection with that form ofovershoe shown in Fig. 1, in that when the spring arms 5 are inoperative engagement with the shoe sole, as shown, the heel of theovershoe is thereby pressed upwardly against the inolosed shoe heel,thus preventing the over shoe heel from slipping down, and therebyobviating one very common cause of wear to the overshoe.

An important function of the spring tongues 7 is to provide that whenthe shoe 1 is inserted in the overshoe 2 the lower edges of the shoesole will engage the upper faces of spring tongues 7, thereby springingthe same apart and permitting an automatic engagement of the upper edgesof the shoe sole under the shoulders 6, which operation is particularlydesirable with that type of overshoe shown in Fig. 1.

Of course, when it is desired to remove the shoe, it is only necessaryto slip the finger inside the ov'ershoe and press lightly upon one ofthe outwardly extending spring tongues 7, thus forcing the spring armoutwardly to release the sole of the shoe.

I claim as my invention:

1. The combination with an overshoe, of a plate engaged therein, alaterally directed spring arm on each side of said plate, each armembodying an inwardly directed shoulder adapted to positively engage thesole of a shoe when the overshoe is in place thereon, and an outwardlydirected tongue formed integral therewith.

2. The combination with an overshoe, of a spring plate engaged thereinand extending longitudinally of the sole thereof at approximately thearch andin the curve of said arch, a laterally directed spring arm oneach side thereof, each arm embodying an inwardly directed shoulderadapted to positively engage the sole of a shoe at the arch when theovershoe is in place thereon,

and an outwardly directed tongue formed 15 SIMON J. McCANNl Witnesses:
